Why?

It should be copying subvars to the new vectorizer variable too.
At least, i believe i added that.

Where would I look for that code?  I'm totally unfamiliar with the
vectorizer code.


finalize_ssa_stmt_operands () copy V_MAY_DEFS from old v_may_defs
vector. I do not see update_stmt() in my copy of check-out.
You probably meant modify_stmt(). Otherwise I am not up to date on this.
